4.4.1 Introduction
4.4.2 Constant Voltage Operation
4. For fine adjustment of output voltage, press V/A consecutively until the V LED illuminates and the
4. For fine adjustment of output current, press V/A consecutively until the A LED illuminates and the
This paragraph describes the operating modes not involved in programming the power supply via it’s
serial communication port. Operation utilizing the front and rear panel are described in this paragraph.
For information regarding serial port usage, please refer to chapter 5.
The REM LED on the front panel indicates whether the power supply is in Local or Remote mode. The
extinguished LED indicates Local operation. If the LED illuminates, the REM pushbutton (fig.4-1, item
8),should be pressed to change the operating mode to Local.
1. In constant voltage mode, the power supply maintains the output voltage at the selected value while
2. While the power supply is operating at constant voltage, the CV LED on the front panel illuminates.
3. For coarse output voltage adjustment, press V/A consecutively, until the V LED illuminates, and
3. For coarse output current adjustment, press V/A consecutively, until the A LED illuminates, and
The maximum and minimum setting values of the output voltage are limited by the over voltage and
1. In constant current mode the power supply maintains the output current at the selected value, while
2. While the power supply is operating at constant current, the CC LED on the front panel illuminates.
